SOLE-CHANNELING AND FLAP-TURNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 615,015, dated, November 29, 1898. Application filed March 26, 1898. Serial No.'675,24=2. (No model.)

To all whom it may concern:

Be it known that I, HANFORD T. ORosBY, of Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Sole-Channeling and Flap-Turning Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to sole-channeling and flap-turning machines and is an improvement upon the invention illustrated and described in Letters Patent No. 602,980, issued to me April 26, 1898 5 and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the accompanying drawings and to claims hereto appended, and in which my invention is clearly pointed out.

Figure 1 of the drawings is a plan of a machine embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an elevation of the opposite side. Fig. etis a front elevation. Fig. 5 is a plan of the cutter carrying lever, its vertically-movable support, the pressure-roll, the cutter and flap-turner removed from the machine. Fig. 6 is an elevation of the pendent arm and gage-roll to bear upon the sole edge as viewed when looking at the left-hand side of Fig. 4. Fig. 7 is a rear elevation of the same. Fig. Sis a front elevation of the reciprocating cutter,the flapturner, and the adjustable section of the lever upon which said parts are mounted detached from the machine. Fig. 9 is a rightside elevation of the same. Fig. 10is a leftside elevation of the same. Fig. 11 is a hori: zontal section of the pressure-roll-carrying arm on line no a: on Figs. 3 and 4. p

In the drawings, A is the frame of the machine-head, constructed and arranged to be mounted upon a suitable column or a bench (not shown) in any well-known manner, and A is a stand bolted to said frame near its base in bearings in which is mounted the driving-shaft B, having firmly secured upon one end thereof the driving-pulley O, and between the two bearings in said stand has secured thereon the worm D and has set in or formed upon its other end the crank-pin E only slightly eccentric to the axis of said shaft 13.

F is a shaft mounted in a horizontal position in bearings in the frame A with its axis at a right angle to a vertical plane in which ties the axis of the shaft B and so as to be revoluble and movable endwise in said bearings, and has fitted thereon the worm-wheel G in sucha manner that said shaft and wormwheel are revoluble in unison, and at the same time said shaft may be moved endwise through said worm-wheel. The worm Dengages with and imparts rotary motion to said worm-wheel in the direction indicated by the arrow on Fig. 4.

The rear end of the shaft F is threaded and has fitted thereon the collar I, between which and the rear bearing of said shaft a coiled spring J surrounds said shaft and tends to move said shaft toward the rear. The rear end of the shaft F also has fitted thereon the trunnioned collar K in such a manner that said shaft may revolve therein.

L is an elbow-lever pivotally mounted on the stand M and having one of its arms forked to embrace or partially surround the collar K and engaging the trunnions of the collar K, while the other arm of said lever is connected by the rod or wire N to a treadle (not shown) by which the shaft F may be moved toward the front, when desired, against the tension of the spring J.

The upward movement of the horizontal arm of the lever L and the rearward movement of the shaft F may be regulated by the stop-screw 0, set in the stand 0, and the tension of the spring J may be varied to suit by the nut l and check-nut 1 as shown.

P P is the cutter-carrying elbow-lever, the pendent arm of which is connected by the adjustable link P to the crank-pin E, said lever being mounted upon the fulcrum-pin Q, set in the Vertically-movable slide Q, the upward and downward movements of which are limited by the stops R and R, respectively.

So far the machine is constructed, arranged, and operates substantially as described in my before-cited patent.

I have found it desirable that the feed-disk S should revolve in an inclined plane instead of a vertical plane, as in my prior patent, and to this end I provide the upper portion of the frame A with the forwardly-pro jecting horizontal arm A provided on its under side with a guiding-rib 2, and the front end of the shaft F, instead of having the feeddisk mounted thereon and arranged to revolve therewith, has fitted thereon the stand T in such a manner that said shaft may revolve therein and that said stand shall be moved endwise with said shaft, the upper end of said stand being guided in its endwise movements and prevented from revolving with said shaft by the rib 2, which it embraces, as shown in Fig. l.

The stand T has mounted in asuitable bearing therein the inclined shaft U, upon the front end of which is mounted so as to revolve therewith the feed-disk S and upon its other end the bevel-gear U, which engages with and has motion imparted thereto by the bevel-gear V, firmly secured upon and movable with the shaft F, as shown.

The slide Q has clamped to its upper end the adjustable gage-bar 3, to a groove in the under side of which is adjustably fitted the normally stationary but adjustable cutter 4:, which serves to cut an incision in the sole along the outer edge of the channel and at right angles to the tread-surface of the sole, said parts being constructed, arranged, and operating substantially as in my before-cited prior patent.

The slide Q is provided with the forwardlyprojecting shelf 5 below said gage-bar 3, in the front edge of which is formed a slot in which is adjustably set a stud 6, upon which is mounted the gage-roll 7, and said slide is also provided at a still lower level with the forked arm 8, upon which is mounted so as to be movable toward and from the front the block 9, in which is set a stud upon which is mounted so as to be revoluble thereon the pressure-roll 10, said block and roll being pressed toward the front by the spring 11, as shown in Fig. 11. The outward movement of said block 9 is limited by the pin 12, set in said block, coming in contact with a lug 13 on the plate 14, adjustably secured to the side of said arm 8, as shown in Fig. 3.

V is a lever pivoted at 15 to the frame A and at its inner end to the slide Q and connected at its outer end to the rod 16, the other end of which is connected to a treadle, (not shown,) by which said slide and the several parts carried thereby may be raised at the will of the operator against the tension of a spring connected at one end to said slide and at the other end to the adjusting-screw 18, provided with the thumb-nut 19, as shown in dotted lines in Fig. 1- and substantially as described in my prior patent, before cited.

The portion P of the elbowlever P P is adj ustably secured to the part 1 and has clamped to its front end the cutter 20 in substantially the same manner as in said prior patent and has also secured thereto in close proximity to said cutter the flap-turner 0r channel-opener X, provided on its front face and right side with the shoulder 21, slightly above the lower end of the cutter 20, and with the downwardly-projeeting and backwardlycurved blade 22, the front face of which is also curved transversely, as shown in Figs. 3, 4, 8, 9, and 10.

The shoulder 21, when the cutter 20 descends to cut a section of the channel, engages the upper edge of the section of the flap last previously separated by the cutter and presses it downward and rolls it toward the rear at the same time the blade 22 acts upon a previously turneddown section of said flap to set it in its opened and turneddown position.

The forwardly-projecting arm A has a longitudinal groove formed in its upper surface in which is fitted and adjustably secured, by means of the clamping-screws 23 and the slots 24, the bar Y, the front end of which has formed in one of its vertical sides a rectangular transverse groove or notch in which is adjustably secured, by means of the clam ping-screw 25 and the slot 26, the pendent arm 27, carrying at its lower end the gage-roll 28 to engage the edge of the sole to be channeled and determine the distance of the channel from the sole edge.

The inner face of the feed-disk S has formed therein a circular recess 29, surrounded by the beveled annular serrated surface 30, which engages the surface of the rand or sole to feed it toward the left of Fig. at, the tread-surface of the sole bearing against the rolls 7 and 10 and the edge of the sole bearing against the roll 28, said roll 28 being located between the cutter 20 and the feed-disk S and partially within the recess 29 of said feed-disk.

The operation of my invention will be readily understood from the foregoing without further explanation here. I

\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a sole-channeling machine the combination of the shafts F andU; the feed-disk S carried by the shaftU; the standT; the bevelgears U and V connecting said shafts; means for moving said shafts, stand, and feed-disk in the direction of the length of the axis of said shaft F; the rolls 7 and 10 arranged to bear against the tread-surface of the sole; the vertically and laterally adjustable roll 28 arranged to bear upon the sole edge; the fixed spur-cutter t; the rapidly-reciprocating channel-cutter 20; the flap-turner X; means for vibrating said cutter and flap-turner; and means for imparting rotary motion to said shafts and feed-disk.

2. Inasole-channeling and flap-turning machine the combination of a revoluble and endwise-movable shaft mounted in suitable bearings; a non-revoluble stand mounted upon and movable endwise with said horizontal shaft and provided in its upper side with a guideway-groove; a fixed guide to engage said groove; a feed-shaft mounted in a bearing in said stand with its axis inclined to a horizontal plane; a feed-disk carried by said inclined shaft and provided with a circular recess in its rear or inner face and a beveled and serrated annular surface surrounding said recess; the endwise-adjustable bar Y; the vertically-adjustable pendent arm 27; the gageroll 28 carried by the lower end of said arm; the adjustable gage-roll 7; the yielding pressure-roll 10; a pair of bevel-gears connecting said horizontal and inclined shafts; the fixed gage 3 5 the fixed spur-cutter 4; the reciprocating channel-cutter 20; the flap-turner X provided with the shoulder 21 and the convex-surfaced blade 22; means for imparting rotary motion to said shafts and feed-disk; means for moving said shafts, the stand T and the feed-disk toward and from the front of the machine; means for imparting a rapid reciprocation to the cutter 20 and the flapturner; and means for varying the height of said cutter and flap-turner relative to the lowest part of the feed-disk.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 24th day of March, A. D. 1898.

HANFORD T. CROSBY.
